# What is the next number in the series 7 11 19 35?

67 7 + **4** = 11

11 + **8** = 19

19 + **16** = 35

35 + **32** = 67 the numbers added to the original number are
doubling each time. Double the number, then subtract 3.
7X2=14-3=11

11x2=22-3=19

19x2=38-3=35

35x2=70-3=67 same result, different process.
